APPLICATION FILED MAB. 13. 1906.

Afro/mf ys' To' all w/wm, it may concern:

5 of Indiana, have invented a new and Inproved Column-Clamp, of whichthe following is a full, clear, and eXact description.

This invention is an improvement in column-clamps, and has for anobject, among` others, to provide a clamp which can be easily andquickly operated both in applying to and removing from columns or otherbodies where al lexible clamp is desired. It is especially designed tobe operated by lever mechanism which can be attached and detached afterthe clamp is applied, thereby lessening the weight of the clampedarticle 'and at the same time allowing the lever mechanism to be used inapplying other clamps.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the vfigures.

Figure 1 is a side elevation of my improved clamp and operatingmechanism when applied to a column. Fig. 2 is an end elevation o f theclamp viewed in the direction of the arrow in Fig. 1 when detached fromthe column. Fie'. 3 is a sectional view7 on `an enlarged sca e, on theline 8 3 of Fig. 1; and Fig. 4 is a perspective view of the clampapplied to a .column with the leverapplying mechanism omitted.

The numeral 1 indicates a bar having a hooked member 2 at one end andpins 3 near each end passing through the bar and projecting beyond eachside thereof. Between the pins 3 is slidably mounted on the bar 1,through a slot 4, a clamping-block 5, bifurcated at its lower end at 6,through which extends a in 7 for connecting a chain 8 or lile'connection with the hooked member 2, as best shown in Figs. 1 and 4 Thepins 3 are for limiting the movement of Specification of Letters Patent.

tached from Vthe bar and used for as many clamps as desired. mechanismconsists of levers'9 and 10, pivotally attached"y to a supporting-block11 by pins 12 and 13, respectively. The 'block 11 is bifurcated at itsupper end for containing a cam 10a at the endof lever 10, and the leveris provided with a pin 14 for contactin in a recess at the upper end ofthe block in order to limit its movement in the direction of lever 9.The block 11 near its center has a slot 11, enlarged at both'sides,forming a prolongation of the bifurcation at the upper end of the block,the enlargements'permitting the block to be slipped on the bar 1 pastthe pins 3. The lever 9 at the point 15 applying is made up of twobranches 9a to permit vthe bar 1 and block 11 to pass therebetween inorder that it may vnot contact with the 4bar and can be pivotallyattached t the su 11 at each side and below t e'f' ortinq-block ar 1 bythe pin 12. Each of the branches 9a beyond the pivotal connection 12 isprovided at its end with a cam 16 for forcing the clamping-block alongthe bar 1 when the supporting-block 11 is secured thereto.

To operate the clamp, the chain 8 ispassed and pulled tight about thebody desired to be clamped'and the hooked member 2 connected to theadjacent chain-link 8a. The supporting-block 11 is then slipped over thebar 1 and placed as close to theclamping-block 5 as convenient. Thelever is then asped by the left hand and pushed from the ever 9, which,through cam 10, clamps the block 11 to the lbar 1. At this point thelever 9,

vwhich is held by the ri ht hand, is ulledA in the opposite direction,orcing the c ampingblock 5 at its bottom toward the The clamping-blockWill not when forced in this position slide backward on the bar 1 onaccount of the bight formed between them at the point 5a. This operationof the lever mechanism can be repeated, if necessary, by slidin ittoward the` block 5 when released from t e bar 1 and clamping it in itsnew position to exerturther tension on the chain 8. The block 11 isthenreleased from the bar 1 and with the attached levers 9 and 10slipped from the clamp and can now be used for applying any otherclamps, if desired. When it becomes'necessary to remove the clamp fromthe body to which it is attached, strike the upper edge of theclampingblock 5 with a hammer at the point marked 18, which disengagesthe bight 5a,al1owing This lever hook 2.

It is evident that numerous changes and modifications can be made in thestructure hereinbefore described, and I desire to haveit understood thatIclaim all such as fall within a fair interpretation of the annexedclaims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination of a bar, a hook at one end of thebar, a clamping-block slidable on the bar, means for limiting themovement of the clamping-block on the bar, a flexible connection betweenthe hook and the clampingblock, a supporting-block slidable on the bar,a lever pivoted at each end ofthe supportingblock, and a cam .carried atthe end of eac lever, one of said cams for clamping the supporting-blockto the bar and the other of said cams for forcing the clamping-blocktoward the hook.

2. The combination of a bar, a clampingblock movable with respect to thebar, a flexible connection between the bar and block, a supporting meansapplicable to the bar, a lever having a cam clamping the supportingmeans to the bar, and a second lever pivoted to the supporting means foroperating the clamping-block.

3. The combination of a bar, a clampingblock slidable on the bar, aexible connection between the bar and clamping-block, asupporting-,block adjustable on the bar, means for clamping thesupporting-block to the bar, and means carried b the support ing-blockfor operating the c amping-b ook.

4. In a clamping device, a bar, a clampingblock slidable on the bar, aflexible connection for connectin the bar and the block, asupporting-block s idable on the bar, a lever pivoted at each end of thesup orting-block,

and means whereby when one ever is moved in one direction thesupporting-block is secured to the bar, and when the other lever ismoved in the opposite direction, the clamping-block is moved on the bar.

5. The combination of a bar, a clampingblock slidable thereon, meansconnecting one end of the bar with the clamping-block, asupporting-block adjustable on the bar, means carried by thesupporting-block for clamping it in adjusted position on the bar, andmeans carried on the supporting-block for operating the clamping-block.

6. The combination of a bar, a clampingblock slidable thereon, means forlimiting the sliding movement of the block at each end of the bar, meansconnecting one end of the bar with the clamping-block, asupporting-block adjustable on the bar, means carried by thesupporting-block for securing it in adjusted position on the bar, andmeans carried on the supporting-block for operating the clamping-block.

7. The combination of a bar, a clampingblock slidable thereon, aflexible connection connecting one end of the bar with one end of theclamping-block, a supporting-block adjustable on the bar, a lever havinga cam pivoted in the supporting-block for locking the supporting-blockin adjusted position, and a second lever pivoted to the supportingblockhaving a cam end for bearing on the clamping-block, for sliding it onthe bar, for the purpose described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
